Prince2 is a project management framework that's popular in government. This 11-hour course claims to be able to get you through the exam.
I've had a (quick) look at the course material, and it's taught by an actual training company, and seems no worse than some of the paid courses I've attended. It's getting decent ratings in the comments too.
I've also searched on Ozbargain, and I don't think it's been posted before. There's a Learn the basics of Prince2 course in WNK's monster Free 200 Online Courses post, but it's a different course.
We need a "search by vendor" option in the advanced search on OzBargain, to make searching for dupes easier. Searching "prince" gets EB's Prince of Persia sale, etc.; being able to scope it to a URL would help.
Highly doubt anyone could use this (or any other guide for that matter) and pass after 11 hours. Of course, that's not what anyone sitting the exam will expect anyway.
It will probably be handy as a study guide and certainly deserves a +1. Anything on PMBOK would be great too!
